IMPROVEMENT IN PIPE-MOLDING MACHINES.

Specification forming part of Letters Patent No. 129,547, dated July 16, 1872.

To all whom it may concern:

Be it known that we, JAMES T. GLASS and Lnwrs E. MORRELL, of Columbus, in thecounty of Franklin and State of Ohio, have invented a new and valuable Improvement in Pipe- Molding Machine; and we do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawing making a part of this specification, and to the letters and figures of reference marked thereon.

Figure 1 of the drawing is a representation of a sectional view of our invention. Fig. 2 is a plan view of our invention.

Y This invention has relation to pipe-molding machinery; and consists in the construction and novel arrangement of devices for feeding the mold-packer, as-hereinafter more fully described.

Referring to the drawing, A designates an upright frame, supporting a horizontal platform, B, recessed in front at A for the reception of the packer-shaft and collars, and provided with the standards 0, holding a pulley and worm-wheel shaft, D. E represents a wormwheel, and E E a double Windlass-pulley, placed on the shaft D. The wheel is rigidly secured to the shaft, but the pulley is loose, and adaptedfor coupling with the shaftthrough the medium of a sliding clutch, G. The cord H, from the pulley, passes over a sheave, I, at the top of the frame A, and connects with a cross-head, I having recessed ends to slide on vertical guides I and connected to the upper end of the rotary packer-shaft 1 Upto revolve and feed upward, leaving the sand firmly packed inside the flask. The shaft I is constructed with a feather, N, and passes through a sleeve, 0, correspondingly channeled, and adapted to rotate with said shaft. This sleeve is supported 'by brackets P, attached to the platform B. The upper and lower ends of said sleeve are provided with slotted brackets P holding friction wheels P I, working against the shaft 1 according as the latter works upward or downward. The rollor I is grooved and works in contact with the rounded part of theshaft, the others touching the feather. The sleeve also holds a bevelgear wheel, Q, which engages with a pinion, Q, on the end of a shaft, R, having a worm,

R, working in connection with the worm-wheel E, and operated by means of a crank, S, or otherwise. By reason of the bevel-gearing and pulley connection the rotation and feed of the packer-shaft are simultaneous. To facilitate the lowering of the shaft the pulley may be disconnected from the clutch. The shaft will then fall by its own weight.

The object of a double pulley is to provide for a change of speed of the feed in its relation to the rotary motion of the shaft.

What we claim as our invention, and desire to secure by Letters Patent, is-

1. The channel-sleeve 0, provided with the slotted brackets P having friction-wheels P F, in combination with the vertically-feeding feathered packer-shaft I substantially as specified.

2. The combination of the shaft 1 sleeve 0, gearing g g, worm-wheel and worm E R, pul- -leysE E and cord H, substantially as spec-
